Abstract

Lorsqu'une application de confiance et un programme d'aide au téléchargement sont exécutés sur un téléphone mobile (600), un message de demande de réservation de zone est produit pour solliciter la réservation d'une zone de stockage destinée au stockage d'un programme et de données. Le message est transmis à un serveur gestionnaire de zone (500). A réception du message de réservation de zone, le serveur (500) transmet un message d'instruction de réservation de zone au téléphone mobile (600). Lorsque le téléphone mobile (600) reçoit le message d'instruction de réservation de zone, une zone de stockage destinée au stockage d'un programme et de données est attribuée dans une mémoire externe, puis le programme et les données téléchargés sont stockés dans cette zone.
